Application filed January at, 1913. serial no. nieces.

. the panes of glass can be replaced without disturbance to the paneslying between the same sash bars. ThlS I obtain by providing a channeledbar between every two consecutive panes of glass lying between the samepair of sash bars. This metallic channeled ar is attached to andsupported by the sash bars, and constitutes a bed for putty which formsa seal between the juxtaposed ends of the panes of glass.

Reference is to be had to the accompanying drawings forming a part ofthis specification, in which like characters of referthis concavesurface and engaged .in the the said channeled ence indicatecorresponding parts in all the views, and in which Figure 1 is alongitudinal section of the roof of a greenhouse embodying my invention;Fig. 2 is an enlarged view of the joint in which the channeled bar ismagnified in thickness; while Fig. 3 is a plan View of a portion of agreenhouse embodying my invention. I

Referring to thedrawings, 10 represents one of the sash bars forming theglazing structure of a reenhouse, Fig. 1 indicating the slope of tie barforming the glazing structure. The sash bar 10 has on each side a.cutout portion forming a shoulder 11 which receives one side of thepanejof glass 12, the other side of thesame pane lying in a similarshoulder of the opposite and parallel sash bar. A channeled bar 13,preferably of galvanized iron, also rests on the shoulders of the sashbars 10 between two consecutive panes of glass. The channeled bar 13 hasits portion resting onthe shoulder 11 preferably c'onvexed, so that theopposite surface is concave, and a brad 14c resting in sash bar 10prevents the dis laceinent of the said channeled bar 13. It s understoodthat a brad 14 is ar. The channeled bar Be it known that I, FRANK VANAssoini,

provided at each end of 13 is also provided with an extending portion15, which is bentso as to contact with the upper surface of a pane ofglass resting on or supported by the shoulder 11 of the sash bar 10. Thelower pane of glass being placed between a pair of sash bars 10 is thenprovided with a channeled bar 13,

which is made to rest with its convex surface on the shoulder 11, itsprojecting portion 15 resting on the'surface of the pane of glass, whilethe edge of the curved portion of the bar 13 rests against the edge ofthe ane. A brad 14 is then forced in place, fittin tightly into theconcave surface of the anneled .bar, to prevent the displacement of thesaid bar. Another pane of glass is then placed on the shoulder-s11,with' its endabutting against the free edge of the channeled bar 13.Then the next channeled bar is placed on the upper end of the pane ofglass, as before descrl ed, and so on, until the space between the twosash bars 1S covered' Then putty 16 is placed into the channeled bars,thereby forming a tight joint between the panes of glass.

The curved portion of the channeled bar 13 lying transversely betweenthe sash bars is substantially flexible in a direction perpendicular toits length, so that the expansion of the glass panes will cause anincrease of the curvature in the curved ortion of the bar, and whencontraction ta res place the bar itself will reduce its curvature andcontact with the ends of the panes of glass.

It will be seen that in my construction for glazing there IS agreatsavingin' glass, as the panes do not overlap one another, as

at present; also, the surface of the lazing is made smooth, andconsequently t iere is less resistance to a blowing wind. The wind willnot have an easy entrance or passage be.- tween the panes in view of theputty 16 sealing the space between the panes. Another advantage of myconstruction is that when a pane of glass is broken the panes lyingabove the broken one'cannot slip down the slope, as each pane of glassissupported by one of the channeled bars 13. The reparation of thestructure is also made eas' ,as

any one of the panes can be readily rep aced without disturbing theother panes of glass. Having thus described my invention, what Iclai'ni'as new and desire to secure by Let-M ters Iatent'issw Ingreenhouse glazing, sash bars adapted to receive'panes of glass, andchanneled bars disposed transversely to said sash bars, said the curvedportion of said bar between the channeled bars being formed of a curvedjuxtaposed ends of the panes 0f--glass, the portion extend'ino to theentire length and said putty formin a seal between said ends. contactingwith the juxtaposed ends of the In testimony w ereof I have signed my 5panes of glass, and a rojecting portion rest name to this specificationinthe presence of 15 mg on the upper sur ace of one of the panes twosubscribing itnesses.
